The Scenario – Build a Bridge
P5c were asked if they could design and build a bridge that would allow all vehicles to cross the river but also allow boats, which may be taller than the bridge, to pass under. The challenge they were set is outlined below and the results and photos of the winning designs can also be found in our blog.
The Challenge
You have ONE HOUR.
Your task is to design and build a bridge which can span across 2 desks and have a way of opening to allow boats to pass under. The bridge needs to be able to support the weight of a small bottle of water without collapsing and open to allow any size of boat through.
The Specifications
Your bridge must:
 Be at least 19cm high (the height of a grey K’Nex rod)
ï‚· Be at least 30cm long (the length of a standard ruler)
ï‚· Have a strong robust structure to stand on its own
ï‚· Be able to support the weight of a small bottle of water or equivalent weight
ï‚· Be able to open to allow tall river vessels to pass through safely.
